Simplify the compile time checks by splittig them into 5 independent checks:

* Whether GCC atomics are available
* Whether pthread_t can be used by GCC atomics
* Whether Solaris libc atomics are available
* Whether pthread_t can be used by Solaris libs atomics
* Checking the size of pthread_t

Include ut0auxconf.h only if none of the macros it would define is defined.
The check when to include this header was outdated from the time when there
was only one macro involved.

Move the atomics checks that are in univ.i outside of
#if windows ... #else ... #endif
This simplifies the code and removes some duplicates like defining
HAVE_ATOMIC_BUILTINS if HAVE_WINDOWS_ATOMICS is defined in both branches.

Do not define the same macro HAVE_ATOMIC_PTHREAD_T for different events.
Instead define HAVE_IB_ATOMIC_PTHREAD_T_GCC and
HAVE_IB_ATOMIC_PTHREAD_T_SOLARIS.

Rename HAVE_SOLARIS_ATOMICS to HAVE_IB_SOLARIS_ATOMICS and 
IB_HAVE_PAUSE_INSTRUCTION to HAVE_IB_PAUSE_INSTRUCTION so they
all follow the same HAVE_IB_* convention.

  branches/embedded-1.0:
  
  Clean up and simplify the code that surrounds the atomic ops:
  
  * Simplify the code that prints what atomics are used:
  Instead of repeating the same conditions on which each atomics are used
  use just one printf that prints a variable defined by the code which
  chooses what atomics to use.
  
  * In os0sync.h pick up each atomic variant only if it has been selected
  by autoconf (based on IB_ATOMIC_MODE_* macros). Define the startup message
  to be printed.
  
  * In configure.in: check what user has chosen and if he has chosen
  something that is not available, emit an error. If nothing has been chosen
  explicitly by the user, auto select an option according to the described
  logic in configure.in.

In case of pages that are not made young the counter is incremented
only when the page in question is 'old'. In case of pages that are
made young the counter is incremented in case of all pages. For apple
to apple comparison this patch changes the 'young-making' counter to
consider only 'old' blocks.

Define HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS in os0sync.h
instead of in univ.i. The code expects os_*() macros to be present if
HAVE_ATOMIC_BUILTINS and INNODB_RW_LOCKS_USE_ATOMICS are defined. So define
them next to defining the os_*() macros.

branches/zip: Avoid bogus messages about latching order violations when
UNIV_SYNC_DEBUG is defined.

sync_thread_levels_g(): Add the parameter "warn".  Do not print
anything unless it is set.

sync_thread_add_level(): Pass warn=TRUE to sync_thread_levels_g()
when the check is within an assertion; FALSE if it is not.

branches/zip: ut0ut.h: Do not #include "os0sync.h" #ifdef UNIV_HOTBACKUP.
Since r5872, the InnoDB Hot Backup build was broken.
Fix it by not defining any thread synchronization primitives in ut0ut.h.
InnoDB Hot Backup is a single-threaded program.
